In a recent study, Haselmayer et al., tested several inhibitors of BAFF or APRIL in a model of mouse autoimmune disease (SLE) to confirm that inhibition of mouse BAFF and APRIL by the receptor TACI-Fc is more efficient than inhibition of BAFF alone or APRIL alone on long-lived plasma cell survival. To block mouse APRIL in this study, anti-APRIL (mouse), mAb (rec.) (blocking) (Apry-1-1) (AG-27B-0001PF) from Adipogen was injected in C57BL/6 mice.
